[PATCH] tpm: remove extraneous #ifdef

[PATCH] tpm: remove extraneous #ifdef

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Changing to DEFINE_SIMPLE_DEV_PM_OPS() broke here because the
tpm_inf_resume() function is hidden in an #ifdef:

drivers/char/tpm/tpm_infineon.c:615:61: error: 'tpm_inf_resume' undeclared here (not in a function); did you mean 'tpm_pm_resume'?
  615 | static DEFINE_SIMPLE_DEV_PM_OPS(tpm_inf_pm, tpm_pm_suspend, tpm_inf_resume);
      |                                                             ^~~~~~~~~~~~~~

Remove the #ifdef check.

Fixes: 2249200ee420 ("tpm: use DEFINE_SIMPLE_DEV_PM_OPS and pm_sleep_ptr()")

I hit the same issue during my build tests. Thanks for your patch.

I pushed this to for-next-tpm, which mirrors to linux-next.

However, since this is -next only bug, I guess I should squash these to
the original commit?

Just sanity checking before taking action :-)

My suggestion would be to amend Co-authored-by to the original commit
message as two bug fixes is significant amount of effort to make the
change right.
